Hello Doctor and thank you for taking my question. My symptoms are skin eruptions, looking and acting much like a chicken pox blister. They are singular, red welts with a blister pocket that itches. They have been occuring about 1 week, lasting about one week. They are on mainly my right arm and arm pit, with only one on the opposite arm and two on my upper chest. I ve had a yeast infection 2 weeks ago. Only other symptom was a slight headcold lasting about 5 days, no fever. I had chicken pox as a child. I am going on a 2 week vacation on Sunday; is this anything to be alarmed about?
